OBJECTIVE: To determine the value of blink reflex in early diagnosis and prognosis evaluation of Bell palsy.
METHODS: Blink reflex and facial nerve conduction were examined in 58 patients with Bell palsy within one week after symptom onset. The patients without response of R1 , R2 and R2 ' waves were classified as complete efferent retardarce (Group A, 30 cases), and those with response of R1 , R2 and R2 ' waves were classified as incomplete efferent anomalies (Group B, 28 cases). The clinical outcomes after three months of systemic therapy were evaluated using the House-Blackmann (H-B) scale.
RESULTS: Efferent anomalies of blink reflex occurred in ail of the 58 patients. Abnormal results of facial nerve conduction appeared in 23 (39. 7%) patients. The three months therapy was effective in 93% patients in Group B and 70% patients in Group A (P<0. 05).
CONCLUSION: Blink reflex can play a significant role in early diagnosis and prognosis evaluation of Bell palsy.
